NON-STAGE TRANSMISSION FOR VEHICLE.

摘要

In a vehicle run by a driving source such as an engine and a motor, a groove width of a drive pulley (19) of a non-stage transmission (B) is increased or decreased by a change gear ratio changing means (61) using a motor (62) as its driving source, so that the change gear ratio of the non-stage transmission (B) can be varied. The motor (62) is controlled in response to output signals from a throttle opening sensor, an engine revolutions sensor and a vehicle speed sensor, thus enabling energy saving operations suitable for the operating conditions of the driving source for running and the running conditions of the vehicle. The change gear ratio changing means (61) is floatingly supported in casings (3, 8) for housing the transmission (B), whereby not only a power unit is made small-sized but also the operating noises of the motor (62) are prevented from leaking to the outside, and moreover, vibrations from the engine and the wheels are prevented from being transmitted to the gear change ratio changing means (61).
